This appears to be related to your question from earlier today, which is here:

You should respond to that one.

As far as this question goes, there is not enough information given to determine a cause of the crash. As suggested in your other thread, you really should contact HP support. That is why you pay them.

Maybe a bad port in SAN switches which can create numerous error messages and cause system crash.

Hi,

Nothing in here confirms what causes the panic, above IO errors could be caused the a storage enclosure or disk connected.

As suggested above try involving HP to take a look at the latest crash dump stored in /var/adm/crash/crash.X (X file number which holds the images of latest dumps).

Best Regards,
Prashanth
